Sequential Design Reliability Studies Measurement Error Biomarkers
2015/3/20
Studies have suggested that oxidative stress might be implicated in the risk of human infertility. For this reason, the BioCycle study, a longitudinal study to assess the effects of endogenous hormone...
Toward a precise measurement of matter clustering: Ly alpha forest data at redshifts 2-4
absorption lines large scale structure of universe
2014/12/26
We measure the filling factor, correlation function, and power spectrum of transmitted flux in a large sample of Lyα forest spectra, comprised of 30 Keck HIRES spectra and 23 Keck LRIS spectra. We inf...
With a high spatial resolution imaging instrument such as the Chandra ACIS, one can confidently identify an X-ray source with only a few detected counts. The detection threshold of such sources, howev...
High-precision measurement of the thermal exponent for the three-dimensional XY universality class
Accuracy of measurement measurement superfluids lipase
2014/12/20
Simulation results are reported for the critical point of the two-component ϕ4 field theory. The correlation-length exponent is measured to high precision with the result ν=0.6717(3). This value ...
Evaluation of roadway Gaussian plume models with large-scale measurement campaigns
roadway Gaussian plume models large-scale measurement campaigns
2014/12/16
Gaussian models are commonly used to simulate atmospheric pollutant dispersion near sources because they provide an efficient compromise between reasonable accuracy and manageable computational time. ...
Statistical Methods for Nonlinear Dynamic Models with Measurement Error Using the Ricker Model
measurement error ricker SIMEX
2014/12/8
In ecological population management, years of animal counts are fit to nonlinear, dynamic models (e.g. the Ricker model) because the values of the parameters are of interest. The yearly counts are sub...
Measurement of the Parity Violating Asymmetry in Elastic Electron Scattering off 208Pb
Jefferson Lab parity violating electron scattering scattering asymmetry neutron skin thickness
2014/11/20
The Lead Radius Experiment (PREX) was carried out in order to provide a model independent measurement of the RMS radius √ < r2 >of the neutron distribution in the 208Pb nucleus. The parity-violating s...
